An extremely sucky feeling that happens to adolescents much too often where your cheeks get all red and you just want to curl up under a dark bed for all of eternity (and/or die in a hole).

Girl: What's wrong, why are you crying?
Other Girl: I just suffered from a high level of embarrassment when my parents showed my boyfriend baby pictures of me! I wish I could curl up in a hole and die!

The shameful feelings that one or a few bad apples bring to their respective race, group or even place.

Cholos like Nortenos, Surenos are an embarrassment to their Mexican race who strive for a better future. Racist whites, white supremacists like the KKK German Nazis are an embarrassment to all Germans. Asian gangsters have become an embarrassment to their own kind who are hardworking people.
